At least 61 suspects were detained across Turkey for selling counterfeit gold in the market, according to security sources on Friday.

The financial crimes police branch in Istanbul uncovered a network producing fake and low quality gold bars in eight different workshops in the city's Fatih district. They were gaining unfair profit by putting it on the market in Anatolian cities.

As a result of the six-month technical and physical follow-up carried out as part of the investigation, the identities and addresses of 103 suspects were determined, said the source on condition of anonymity due to restrictions on speaking to the media.

Police are on the lookout for 42 other suspects.
